This invention relates to a signal transmission apparatus designed for efficient radio signal management in communication systems. The apparatus addresses the problem of optimizing signal transmission and reception by dynamically controlling radio signal states based on input signals and reception status. The apparatus includes a processor connected to a bus wire with a pair of signal lines, a controller linked to the processor, and a transmitter and receiver connected to the controller. The processor generates a logic signal indicating the presence or absence of a signal. The receiver produces a signal representing either a reception flag (indicating successful reception) or a non-reception flag (indicating no reception) based on the received radio signal. The controller regulates the transmission state of the radio signal from the transmitter by processing the logic signal from the processor and the reception flag from the receiver. The controller also receives the logic signal from the processor and the reception flag from the receiver, then generates a logic signal to send back to the processor and a transmission flag to send to the transmitter, enabling adaptive control of signal transmission. This system ensures efficient signal handling by dynamically adjusting transmission based on real-time reception feedback, reducing unnecessary transmissions and improving communication reliability.
2. The signal transmission apparatus according to claim 1 , wherein: in a case where no reception flag is input from the receiver to the controller but the logic signal is input from the processor to the controller, the transmission flag is output to the transmitter, in a case where the reception flag is input from the receiver to the controller and the radio signal received with the receiver is a radio signal transmitted from a communication counterpart, a logic signal is output to the processor, and in a case where the reception flag is input from the receiver to the controller and the radio signal received with the receiver is a radio signal transmitted from the transmitter, a logic signal is output to the processor.
A signal transmission apparatus is designed to manage communication between a transmitter and a receiver in a system where a controller regulates signal flow based on input flags. The apparatus addresses the problem of ensuring proper signal routing in scenarios where a processor generates logic signals for transmission, while also handling incoming radio signals from external sources or the transmitter itself. The controller monitors two key inputs: a reception flag from the receiver and a logic signal from the processor. When no reception flag is detected but a logic signal is present, the controller activates a transmission flag to the transmitter, initiating signal transmission. If a reception flag is present and the received radio signal originates from an external communication counterpart, the controller forwards a logic signal to the processor. Conversely, if the reception flag is active and the received signal is from the transmitter, the controller again outputs a logic signal to the processor. This ensures proper signal routing and prevents conflicts between transmitted and received signals. The system enhances communication reliability by dynamically adjusting signal paths based on real-time input conditions.
3. The signal transmission apparatus according to claim 2 , wherein the controller evaluates whether the radio signal received with the receiver is a radio signal transmitted from a communication counterpart or a radio signal transmitted from the transmitter when the reception flag is input from the receiver to the controller based on the logic signal input from the processor.
This invention relates to a signal transmission apparatus designed to prevent self-interference in wireless communication systems.

When the reception flag is triggered, the controller determines whether the received signal originates from an external communication counterpart or from the apparatus's own transmitter. This determination is based on the logic signal from the processor, which indicates the transmitter's operational state. By distinguishing between external signals and self-generated signals, the apparatus avoids processing its own transmitted signals, reducing interference and improving communication reliability. The invention is particularly useful in full-duplex communication systems where simultaneous transmission and reception occur, ensuring accurate signal processing and minimizing errors caused by self-interference.

Two switching elements are used: a first switching element connects one signal line to a power line (applying DC voltage) and a second switching element connects the other signal line to a ground line. The switching elements are controlled by a driver, which turns them off when a logic signal is received from the controller and turns them on when no signal is received. This design ensures proper signal transmission and reception by managing electrical continuity between the signal lines and the power/ground lines, enabling robust communication in differential bus systems.
5. The signal transmission apparatus according to claim 2 , wherein the controller holds the logic signal to be output to the processor when the logic signal input from the processor to the controller has a state in which no reception flag is input from the receiver to the controller transitions to a state in which the reception flag is input from the receiver to the controller until the state in which the reception flag is input from the receiver to the controller transitions to the state in which no reception flag is input from the receiver to the controller, and the controller outputs no transmission flag to the transmitter.

A signal transmission apparatus is designed to manage radio signal reception and transmission in communication systems. The apparatus includes a receiver, a transmitter, a processor, and a controller. The receiver detects incoming radio signals and outputs a reception flag when a signal is received. If no radio signal is detected, the receiver outputs a non-reception flag to the controller. The controller monitors the logic signal from the processor and the reception flag. When the system transitions from a state where both the logic signal and the reception flag are present to a state where only the logic signal changes, the controller sends a no-transmission flag to the transmitter. This prevents unnecessary transmission when no valid radio signal is received, improving efficiency and reducing interference.
